Methods of Use

The compounds described herein can inhibit the activity of the V617Fvariant of the protein-tyrosine kinase JAK2 (i.e., “V617F” or“JAK2V617F”). Compounds which inhibit V617F are useful in providing ameans of preventing the growth or inducing apoptosis in tumors,particularly by inhibiting angiogenesis. It is therefore anticipatedthat the compounds of the disclosure are useful in treating orpreventing proliferative disorders such as cancers. In particular tumorswith activating mutants of receptor tyrosine kinases or upregulation ofreceptor tyrosine kinases may be particularly sensitive to theinhibitors.

In certain embodiments, the disclosure provides a method for treating aV617F-related disorder in a patient in need thereof, comprising the stepof administering to said patient a compound of the disclosure, or apharmaceutically acceptable composition thereof.

Myeloproliferative diseases (MPD) are multipotent hematopoietic stemcell disorders characterized by excess production of various bloodcells. MPNs include polycythemia vera (PV), essential thrombocythemia(ET), and idiopathic myelofibrosis (IMF). JAK2 V617F mutation isreported in about 95% of patients with PV, in 35% to 70% of patientswith ET, and 50% of patients with IMF.

As used herein, myelodysplastic syndromes are intended to encompassheterogeneous and clonal hematopoietic disorders that are characterizedby ineffective hematopoiesis on one or more of the major myeloid celllineages. Myelodysplastic syndromes are associated with bone marrowfailure, peripheral blood cytopenias, and a propensity to progress toacute myeloid leukemia (AML). Moreover, clonal cytogenetic abnormalitiescan be detected in about 50% of cases with MDS. In 1997, The WorldHealth Organization (WHO) in conjunction with the Society forHematopathology (SH) and the European Association of Hematopathology(EAHP) proposed new classifications for hematopoietic neoplasms (Harris,et al., J Clin Oncol 1999; 17:3835-3849; Vardiman, et al., Blood 2002;100:2292-2302). For MDS, the WHO utilized not only the morphologiccriteria from the French-American-British (FAB) classification but alsoincorporated available genetic, biologic, and clinical characteristicsto define subsets of MDS (Bennett, et al., Br. J. Haematol. 1982;51:189-199). In 2008, the WHO classification of MDS (Table 1) wasfurther refined to allow precise and prognostically relevantsubclassification of unilineage dysplasia by incorporating new clinicaland scientific information (Vardiman, et al., Blood 2009; 114:937-951;Swerdlow, et al., WHO Classification of Tumours of Haematopoietic andLymphoid Tissues. 4th Edition. Lyon France: IARC Press; 2008:88-103;Bunning and Germing, “Myelodysplastic syndromes/neoplasms” in Chapter 5,Swerdlow, et al, eds. WHO Classification of Tumours of Haematopoieticand Lymphoid Tissues.

Synthetic methods for including isotopes into organic compounds areknown in the art (Deuterium Labeling in Organic Chemistry by Alan F.Thomas (New York, N.Y., Appleton-Century-Crofts, 1971; The Renaissanceof H/D Exchange by Jens Atzrodt, Volker Derdau, Thorsten Fey and JochenZimmermann, Angew. Chem. Int. Ed. 2007, 7744-7765; The Organic Chemistryof Isotopic Labelling by James R. Hanson, Royal Society of Chemistry,2011). Isotopically labeled compounds can be used in various studiessuch as NMR spectroscopy, metabolism experiments, and/or assays.

Substitution with heavier isotopes, such as deuterium, may affordcertain therapeutic advantages resulting from greater metabolicstability, for example, increased in vivo half-life or reduced dosagerequirements, and hence may be preferred in some circumstances. (seee.g., A. Kerekes et. al. J. Med. Chem. 2011, 54, 201-210; R. Xu et. al.J. Label Compd. Radiopharm. 2015, 58, 308-312). In particular,substitution at one or more metabolism sites may afford one or more ofthe therapeutic advantages.

The radionuclide that is incorporated in the instant radio-labeledcompounds will depend on the specific application of that radio-labeledcompound. For example, for in vitro V617F labeling and competitionassays, compounds that incorporate ³H, ¹⁴C, ⁸²Br, ¹²⁵I, ¹³¹I or ³⁵S canbe useful. For radio-imaging applications ¹¹C, ¹⁸F, ¹²⁵I, ¹²³I, ¹²⁴I,¹³¹I, ⁷⁵Br, ⁷⁶Br or ⁷⁷Br can be useful.

It is understood that a “radio-labeled” or “labeled compound” is acompound that has incorporated at least one radionuclide. In someembodiments, the radionuclide is selected from the group consisting of³H, ¹⁴C, ¹²⁵I, ³⁵S and ⁸²Br.

The present disclosure can further include synthetic methods forincorporating radio-isotopes into compounds of the disclosure. Syntheticmethods for incorporating radio-isotopes into organic compounds are wellknown in the art, and an ordinary skill in the art will readilyrecognize the methods applicable for the compounds of disclosure.

A labeled compound of the disclosure can be used in a screening assay toidentify/evaluate compounds. For example, a newly synthesized oridentified compound (i.e., test compound) which is labeled can beevaluated for its ability to bind V617F by monitoring its concentrationvariation when contacting with V617F, through tracking of the labeling.For example, a test compound (labeled) can be evaluated for its abilityto reduce binding of another compound which is known to bind to V617F(i.e., standard compound). Accordingly, the ability of a test compoundto compete with the standard compound for binding to V617F directlycorrelates to its binding affinity. Conversely, in some other screeningassays, the standard compound is labeled and test compounds areunlabeled. Accordingly, the concentration of the labeled standardcompound is monitored in order to evaluate the competition between thestandard compound and the test compound, and the relative bindingaffinity of the test compound is thus ascertained.

Kits

The present disclosure also includes pharmaceutical kits useful, forexample, in the treatment or prevention of V617F-associated diseases ordisorders as described herein, which include one or more containerscontaining a pharmaceutical composition comprising a therapeuticallyeffective amount of a compound of the disclosure. Such kits can furtherinclude, if desired, one or more of various conventional pharmaceuticalkit components, such as, for example, containers with one or morepharmaceutically acceptable carriers, additional containers, etc., aswill be readily apparent to those skilled in the art. Instructions,either as inserts or as labels, indicating quantities of the componentsto be administered, guidelines for administration, and/or guidelines formixing the components, can also be included in the kit.

The invention will be described in greater detail by way of specificexamples. The following examples are offered for illustrative purposes,and are not intended to limit the invention in any manner. Those ofskill in the art will readily recognize a variety of non-criticalparameters which can be changed or modified to yield essentially thesame results.
